I understand what you want to do. I have no idea why you want to.   Assuming=
 you have a three wire (plus ground, but I=E2=80=99ll ignore ground) circuit=
 to your crqne, you simply extend it to your other box. Break the tab on the=
 hot side of the outlet, land one leg to each hot screw, neutral to the othe=
r side.  Done. The breaker will take care of overload, it will trip both leg=
s, even if only one is overloaded.=20

Th=C3=A9 problem you are likely to have is you have no neutral at your crane=
, because most motor loads don=E2=80=99t need one.  If you have conduit, add=
ing one is possible and maybe easy. If you don=E2=80=99t, you need to pull a=
 new circuit.  In that cas probably don=E2=80=99t need to share with the cra=
ne.=20
